ReplicatorG can't connect to my Ultimaker


Recommended Posts

Posted · ReplicatorG can't connect to my Ultimaker

Update: The same exact errors occur in both Ubuntu and OS X (10.7.4). I can see the com port and update firmware, just not connect.


I just finished building my Ultimaker and installed ReplicatorG.

I've set the driver and port, but can't get the software to connect.

When it tries to connect I can here the Z motor whirring, but that's it.

ReplicatorG gives the following error:

[22] Ultimaker not responding to RTS reset. Failed to connect after 4 attempts.
[22] Supports RC

Any thoughts?

    Note, unless you running an outdated version of Linux, Cura should never "core-dump" as that indicates a bug in python or your OS.

    You could also have general hardware problems with your machine. But that's just a random guess.

    I managed to get Crua 12.07, and RepG, working under OS X.

    The NetFabb demo connected on the first try.

    I still can't get Cura 12.08 to work though. When I try to connect to the Ultimaker in the first run dialog the motors tense up every few seconds and then I get the error above.

    I'll poke around when I have a moment and supply more info, but I believe that I'm running the latest version of Ubuntu (in a VM). I'll try re-installing Python as well.

    Now that this seems to be isolated to a problem with Cura, can this thread be moved to the appropriate area?

    I checked my OS X install and it looks like the only version of Python installed is 2.7.

    Slicing to gcode, hitting print and then connect produces the following in 12.08. 12.07 still works fine for me.
